If you smear a thin coat of woodworkers glue on one side of a piece of finish plywood say 4x4 inches ,have you insulated that surface side electrically or partly??

Wood is a natural insulator as long as it's dry, but no...a smear of glue won't cut it. You would need to use some sort of non-conductive sheet such as plastic or rubber.

Why would you be trying to do this? Details always help get informed replies.

You would have insulated it to some degree, but no one outside of a testing laboratory could really say how much. It would not be legal to use as an insulator in any premises wiring system.
